To all whom it may concern:

Be it known that l, ARTURO Sonet, ject of .the King?T et italy, residing lingerie, Switzerland, have invented new and useful Improvements in New Elastic l,Wheels l' Automobiles and other lfeliieles, et whLi the following` a specification.

The' inventien tanning the suliijeet of the present application relates to various improvements in wheels which are specially intended for: the ,class et vehicles to be driven at high speeds and for light vehicles, and is hereinafter described and illustrated in the accompanying drawings, in which- Figure l is a side elevation of the Wheel with a part in internal section. Fig. 2 a transverse section et the wheel. Fig. f3 illustrate; the aluminium rings a and with which the wheel is provided in side elevation, such rings being formed on one ot their faces with recesses c constituting seats; Fig. 4 is a longitudinal side sect-ion of one of the india rubber cylinders h fitted with a metallic attaching connection to be hereinafter described. Fig. 5 is a transverse iront section of one of said cylinders i.

In these figures l is a solid indiay rubber tire, applied te the steel rim e, and secured by means of dovetailed projections f. The ring ,7) is of aluminium and on its inner 'face it is formed with recesses rf constituting seats corresponding in position to seats formed on the outer face of the, aluminium ring a., as shown inFige 3. Between these seats is an intervening' space :7, y, t the form illustrated in the drawing. into wl'iich the india rubber cylinders ."i are introduced with their at right angles tn the 'face of the wheel.

The inner tace oi the a is by means of screws secured to Lz .vnocien ring e which by means et tiaprojcctiens E spokes m ot the Wheel the are ettaehed, terminating in a removable metallic hub n.

The Figs. 4 and illus; are the method in which the cylinders showniie Fig. S are arranged in the seats c. The. pivot-s 0 inserted in specially formed openings in the cylinders pass through a small pin 77, the extremity of which is traversed by other pivots q, and articulated tothe two rings rf, and l5. To the two sides of the rim i by m is pivots s, two bronze plates r are secured, the faces of which have the geometrical ligure of a eircular crown; These 'plates 1' are in frietional contact with the steel plates-t of the same form. They are secured te the. ring Z2 by means et belts u. The plate l itil-filed on the riglt hand `side looking' at Fig. ifi, ot

l larger ,liaiucter than that of the ring sind is ite-Cl in recess in the riin e, wl'iercff': hat. on tne left hand is of an enter diameter equal te thatv of tl'ie ring 5, ll`he nuts i oi the u are situated on the side et this latter circular crown (left hand). Four of these bolts beneath-their nuts` carry a washer, one part of the diameter of which lit-lars on the eide et the rin: e, anti in siiecially termed recess. This: system 'permits' of the rim e being remo-veil rapidly :is possible, when the india rubber tire d has to be renewed, without havingf to flisniount the wheel, or to remove the eirculal crowns, which is due te the tent nuts e ot the bolts u filtei'l with washers, n'hich hold them in place. preventing all movement et it.

The. elasticity of the wheel described insured by the cylinders by reasonet' saine being of india rubber .fi nl that they :ire provided uith n cmi ral op-.rnin'er iu, which permits of the maximum iatenine' iuoven'icnt. The recesses e cnnstitui :cat:-` situaicd between tbe tno ringsv :in-:l c', zinfl inclosing the cylinderf-f, present very iinpml'ant aflvantages.

verified owing to the said seats which are displaced in a contrary direction to each other and exert pressure at their angles on all the cylinders .7a. The openings w of said cylinders 7i. permit oth the adjustment of the elasticity of the wheel to suit the weight of the vel cle to which the wheel is applied; this adjustment is obtained by making the openings Ismaller or larger.

That I claim as Iny invention, `and desire to secure by Letters Patent, is-

ln a. Wheel for automobiles and other vehicles, in combination, two concentric rings spaced from one another, a tire secured to the outer surface of the outer ring, the inner ring being secured to the hub of the wheel, the oppositely disposed faces of said rings being provided with annular members having recesses formed therein, the recesses in said annular members registering with one another in pairs, hollow resilient cylinders positioned between said members, there being one cylinder engaging each ofv said pairs of recesses, said cylinders having their longitudinal axes parallel to the axis of rotation of the Wheel, longitudinally disposed pivots positioned within said cylinders adjacentl their inner and outer surfaces, pivots positioned within said annular members and extending in parallelism with the pivots in the cylinders, and pins connecting the pivots in the outer and inner members` With the pivots adjacent the outer and inner surface of the cylinders respectively.

In testimony whereof I have signe-d my name to this specification in the presencev of two subscribing Witnesses.
